Is it the d-d transition of electrons that imparts color for an object?

Yes, as an electron returns from a higher energy state to a lower energy state, it emits a photon with energy equal to that of the difference between the 2 states, which is responsible for color. Thanks

But, How does an electron regains its excited state after the emission of a photon?
